Torrefaction is one of the pretreatment processes used to overcome the disadvantages of using biomass as a fuel such as low energy density, high moisture, and oxygen contents. The torrefaction increases energy density, hydrophobicity, and reduces grinding energy requirement of biomass. This paper provides a review of the recent advancements in the torrefaction process. The discussion will cover the environmental and economic aspects of the torrefaction process and torrefied pellets, and various applications of torrefaction products. The cost competitiveness of torrefied pellets is one of the major concern of the torrefaction process. Integrating the torrefaction with other processes makes it economically more viable than as a standalone process.
热解是克服生物质作为燃料的一些缺点的预处理工艺之一，这些缺点包括能量密度低、水分和氧含量高。热解可以提高生物质的能量密度、疏水性并降低其研磨能耗。本文综述了热解工艺的最新进展。讨论内容将涵盖热解工艺和热解颗粒的环境和经济方面，以及热解产品的各种应用。热解颗粒的成本竞争力是热解工艺的主要关注点之一。将热解与其他工艺集成比单独使用热解更具经济可行性。
